T ail nborn it may concern:

Be itknown that 1, ROBERT C. STEVENS, a citizen of the United'States, residing at Erie, in the county of Erie and tate of Pennsylvania, have invented certain new and useful Improvements in Steam-Superheaters; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 'appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to steani super-heaters and has for its object the arrangement of a super-heater apparatus in combination with a setting of a steamboiler, in such a manner that a portion of the gases of comafter set forth and described andare i1lus-- bustion maybe deflected through the superheating apparatus when desired.

The features of my invention are hereintrated I in the accompanying drawing in which:

Figure 1, 1s a longitud nal vertical section of a boiler setting and super-heating appainpm'spective of the "ratus, on the line ."c-w, in Fig. 2, embodying my invention.- Fi mfi, is a transverse section of the same on the line y-y, in Fig. 1. Fig. 3, is a perspectiveview of a portion of the super-heating apparatus removedfrom its setting. Fig. l, is a View headers of my improved super-heater, disconnected therefrom. Fig. 5, is a fragmentary view showing the manner. in v rich the tubes are secured in the header of my improved superheater. X

In these-drawings A, indicates a tubular steam boiler, A, indicates a furnace chamber thereunder, 42, indicates the combustion chamber, a, indicates the grate bars, a, indiy mates the fire-wall at the back of the furnace within vthe,chamber B, I place a supenheating apparatus G. Within the chamber 13, I also construct a bafiie wall (1. The cham- Specification of Letters Patent.

ber B, is closed at the rear end by means of a door 13*. From the chamber B, a draftduc 1), leads to the smoke-stack E, and in thisfiuel), I provide a damper mechanism (Z, and in the Smokestack E, provide another damper mechanism a. The construction of the super-heating apparatus C, is illustrated in Figs. 3, 4 and 5, as follows, viz :C, indicates U-shaped tubes, which are secured in plates 0 and C in the usual manner, as shown in Fig. 5, said plates C and C", being provided with tap-bolts c, as shown in Fig. 1 Against 'the faces of the plates C rind C I secure, by means of said tap-bolts c, headers F, and F, which headers are provided with internal division Walls F and F which walls contact with the faces of the plates (laand C and when in place against said plates, said headers form two inclosed chambers, each. Steam is admitted through the pipe G, of the header F, into the upper chamber f, and thence into the upper tubes 0, in the plate C ,'and it.

passes though the tubes G into the chamber f, in the header F from which chamber f; it passes into the tubes 0 from Which tubes 0 the steam passes into the chamber P, in the header F, andthence into the tubes 0 and into the chamber f, in the header F, and thence out through the pipe G.

In operation, when it is desired to superheat steam, the damper (Z, in the draft-flue- D, is opened, and a portion of the gases of combustion are thereby drawn from the combustion chamber A through the opening B and around the ballie-wall C, in the the volume of said heated gas being regulatecif by the opening or closing of the dam- From the foregoing description, the con- /struction and operation of my improved super-heater will be obvious, and further description thereof is deemed unnecessary.

Therefore having fully described my inventionzso as to enable others to construct and operate the some, What I claim as new chamber B, and out through the sinoke flue and desire to secure by Letters-Patent is v 1.
